The article considers issues of efficiency of application of the high-speed automatic transfer switch devices in case of interruptions of the external power supply to main technological power consumers at booster compressor stations fed from two independent sources. The basic schematic solutions of power supply systems for booster compressor stations are described, the most frequent critical operating modes of power supply systems of stations are marked. We analyzed the models of transient processes of the main electric consumers at failure of external power supply. Critical parameters of power supply system operation, under which an electrically-driven gas compressor unit maintains stability of operation, have been determined. It was assessed the possibilities and efficiency of application of a high-speed power recovery device at a booster compressor station with synchronous electric drive of a gas compressor unit under operating production mode. Achieved parameters of power supply system operation are given. Their comparative analysis with a previously developed model of transient processes is performed.
Practical conclusions have been made on efficiency and expediency of application of high-speed automatic transfer switch devices at booster compressor stations with electrically-driven gas compressor units, which indicate an increase in dynamic stability of units’ operation, increase in operating life, and reduction of time for operational control of the units.
